Devices That Use High Voltage Contactor

By William McDonald


Electrical components carry current that needs to be controlled regularly. For this reason, there ought to be components connected to devices transmitting electricity. Markedly, a high voltage contactor is used to regulate current by allowing devices to be switched on and off. Various devices that must have fuses are explained in the paragraphs below.

Three elements work together to allow full functioning of fuses. These components are a coil, pole, and auxiliary. To start with, valves are switched on and off by coils. They are spiraled to reduce the distance traveled by signals, hence allow faster action. Poles transmit power signals to fuses. Finally, auxiliaries are used for paneling as well as indicating circuit application.

Connectors are commonly applied in the paneling of lighting. Large buildings such as commercial as well as offices require that lighting is controlled from a central point. Great current switches are best suited for this due to their ability to transmit strong electrons. Since coils may consume more power in such applications, latching valves are used instead. These have two coils. One is powered temporarily hence suited for closing circuits. The opening coil is suited for establishing connections.

The other usage is in vacuum contacts. These are specialized switches whose valves are compressed in vacuum containers. During transmission, these valves are pushed by suppressing arcs. They become smaller hence occupy little space than before. This makes it possible to transmit huge currents at the same time. Since switches are internal and need no air, vacuum switches can be used in dirty surroundings such as in mining. This is because they can easily move circuit breakers immersed in oil. Likewise, electric signals are easily broken hence applicable in fast lighting elements.

Mercury transmitters also utilize connectors. Electric signals in such devices are moved through liquefied mercury. Since mercury reacts easily with air, it is contained in an airtight container. Containers are further lined with insulation materials to prevent heating. For this reason, cycling surfaces which easily corrode with time may utilize such valves. However, usage of mercury relays is reducing since mercury is not environmental friendly. Solid connectors are used in place of these.

A different version of mercury transmitters is mercury wetted relays. These minimize the amount of liquefied mercury infuses. Unlike in mercury relays, valves are coated with a little mercury before use. For this reason, they cannot relay greater capacities compared to other connectors. As a matter of fact, their carrying capacity is limited to 15 amps and below.

Another usage is in camshafts also known as transformers. Camshafts are special transmitters that utilize numerous circuits aligned sequentially. Electric magnets would be best, but they cannot be used individually. Switch efficiency in transformers is more improved since electric current may be powered by electric motors or gas cylinders. Initially, camshafts were widely used to speed up electric locomotives.

Connectors may also be used in magnetic starters. These devices are important in starting electric locomotives. Valves are used to control the amount of energy transferred through coils. At any given time, contacts may not overload. For this reason, they are best for the provision of automatic circuit breaking.
